| MDL Heavy Industry Weigh Belt |
MTF Weigh Belt Low to Medium Capacity Feeder |
MWF-101 Light Industry Weigh Belt Feeder |
MDL Weigh Belt is widely recognized mainline industrial continuous weigh belt feeders. They can be used with an open loop belt drive to gravimetrically totalize and measure the flow of material, or with closed control as a feeder and regulate the flow to a constant or varying set point. MDL bridges the gap between standard low capacity and high capacity weigh feeders. Some materials are too abrasive for standard low capacity feeders, lump sizes can be too large or flow rates slightly exceed specified limits, resulting in low accuracy and constant maintenance problems. These applications often can’t be reliably handled by larger, high capacity weigh feeders because the relatively low flow rates fall below specified limits. (for example: feeding 1.5 lumps of coal @ 2 STPH). The Model MDL is as ruggedly built as our capacity weigh feeders, to withstand abrasive materials, but is designed to operate at flow rates just beyond the limits of our low capacity feeders.

“MTF” weigh feeder is a low to medium capacity feeder that accurately and reliably measures and controls material feed rates. It is available in widths from 18” to 48”, with different belt types, standard inlet configurations and materials of construction to meet the most demanding requirements. Each weigh belt feeder can be adapted in length and width to meet the customers’ specific requirements. Modular construction features open design or completely dust tight enclosure. Material containment is achieved using full length adjustable skirt boards installed along the entire length of the conveyor or with high side wall belts made of corrugated high-tensile rubber which provide excellent flexibility, elongation and abrasion resistance. The two options can be combined for highly free flowing materials.

MWF-101 Weigh Belt Feeder provides Thayer Scale accuracy, ruggedness and reliability and reduces measurement errors. Self cleaning pulley eliminates material build-up and belt tracking problems. Unique flared skirt design prevents material spillage and assures proper feed control. Rigid scale support system provides exceptional stability, assuring accuracy without frequent re-calibration. Belt velocity is measured from the tail pulley, not the drive motor, providing a direct measurement of belt speed which improves both measurement and control of the material. Totally enclosed, gasketed design assures safe, dust free operation even when handling fine powder. The strain gauge load cell assembly can be easily removed then reinstalled without re-calibration of the feeder.Standard design coupled with dimensions and rates that are tailored to each application add versatility to its capabilities. Its design for ease of maintenance and the ability to change its throughput rating gives it a long useful life in a rapidly changing industrial environment

| MXL-LD Low Density, Light Loading Weigh Belt |
SI Insertion Weigh Belt |
M-LD Low Density, Light Loading Weigh Belt |
Thayer Scale’s Low-Density “MXL-LD” is the only low capacity weigh belt feeder designed specifically to handle low bulk density materials. Because the weigh sensing system in the Low-Density Model “MXL-LD” is engineered exclusively for these types of materials, it can deliver consistent, accurate long term performance. Thayer Scale engineers developed the technology for reliable weigh feeding of low-density materials. In these specialized applications, our Low-Density Weigh Belt Feeders have a proven record of being significantly more reliable and accurate than “standard” weigh belt feeders. |
Thayer Scale’s Weigh Belt Feeder Series “SI” Insertion Weigh Belt Module is a unique feeder that has been designed to easily fit into an existing belt or vibratory conveyor line. The “SI” comes in either scale over or scale under design. A short support framework and a V-Guided conveyor (12, 18, 24 and 36 wide) makes this the only practical weighing module for insertion into a transition space between existing conveyors or equipment.

Thayer Scale’s specialty equipment lines is the Model “M” Low-Density Feeder line for weighing bulk materials having densities under 10 lb/ft3. A conventional feeder capable of weighing heavier products (typically 50 lb/ft3 and above) to an accuracy of ½% under limited weekly calibration attention, is likely to achieve no better than 3-4% accuracy when weighing a material having a density of only 5-10 lb/ft3 .High accuracy, rugged measurement system 100% of the scale’s capacity is used to weigh material. Dead weight of the weigh idler and belt is mass-counterbalanced, thus providing excellent resolution and a high signal to noise ratio. Thayer Scale’s rugged load cell design assures reliable and accurate performance for the life of the weigh feeder. |

| MD Heavy Industry Weigh Belt Feeder |
MWF-OS Light Industry Weigh Belt Feeder |
MS & SB Weigh Belts |
MD Weigh Belt Feeder is widely recognized mainline industrial continuous weigh belt feeders. They can be used with an open loop belt drive to gravimetrically totalize and measure the flow of material, or with closed control as a feeder and regulate the flow to a constant or varying set point. MD is an extremely rugged weigh feeder that was originally designed for the harsh environment of the cement industry but can be used in a wide variety of applications. The Model MD is the ideal weigh feeder when medium to high feed rates are required, handling high bulk density and small through large particle size materials. The Model MD can be subjected to extreme environmental conditions such as abrasive dusts, corrosive fumes, wide temperature fluctuations and vibrations-without any detrimental effects on performance or accuracy.

MWF-OS Sanitary Open Construction Weigh Belt Feeder provides Thayer Scale accuracy, ruggedness, and reliability.Self cleaning pulley eliminates material build-up and belt tracking problems. Unique flared skirt design prevents material spillage and assures proper feed control. Rigid scale support system provides exceptional stability, assuring accuracy without frequent re-calibration. A standard design coupled with dimensions and rates that are tailored to each application add versatility to its capabilities. Its design for ease of maintenance and the ability to change its throughput rating gives it a long useful life in a rapidly changing industrial environment.

Simplified construction and calibration results from suspending a complete synchronous-speed conveyor from a THAYER Flexure Scale. The type “S”, “SB” units adapt well to existing vibratory, screw or belt conveyor installations where it has been determined that weight measurement and/or flow control is desired. Also on new installations, the combination of a suitable pre-feeder and type S, SB unit often proves the best approach considering both cost and material handling requirements. The type “S”, “SB” has been used to handle, rock wool, aluminum chips, hot rubber extrusion, glass cullet, ice, sand and petroleum coke. |

| MDH Heavy Industry Weigh Belt Feeders |
MWF-ES Light Industry Sanitary Weigh Belt Feeder |
MH Heavy Industry Weigh Belt Feeders |
Originally designed for steel mill service, Thayer’s Weigh Belt Model MDH benefits put it into a class by it self. The Model MDH offers an extremely robust design with an intense commitment to quality and attention to detail. With over 60 years of weigh belt experience THAYER produces a weigh belt that is highly accurate, rugged and dependable. THAYER feeders are built to endure the rigors of high capacity feeding and heavy density materials ranging in particles sizes from fines to 6″ lumps.

The S52c Instrument can be used on most Weigh Belt and Loss-In-Weight Feeder systems to provide continuous control and information about the flow of material to its process by monitoring the load and speed. The weigh system can use either a strain gage or LVDT Load Cell to sense weight; however a variety of sensors can be used to sense the speed. Weight information on a Weight information is processed as weight per length and speed is processed as unit length per time. Integrated together, this information is processed by the controller portion of the instrument to provide continuous control of the system to match a target flow rate or set-point. |
